摘要
车辆的高机动性和复杂的无线环境对6G车联网数据传输提出了巨大挑战。基于高吞吐量毫米波通信,车辆可将数据流量机会式卸载到相邻近路侧设备(Road Side Unit,RSU)。针对下一代车路协同业务场景,分析了RSU位置部署问题,提出了一种改进的贪婪算法。使用真实出租车轨迹集综合仿真RSU部署方案,在预算限制内提高RSU利用率并减少车辆的接入等待时间。
The high mobility of vehicles and the complex wireless environment pose great challenges to the data transmission of 6G Internet of Vehicles.Based on high-throughput mmWave communications,vehicles can offload data traffic to adjacent Road Side Unit(RSU)in an opportunistic way.For the next-generation vehicle-infrastructure cooperation scenario,the location deployment of RSU is analyzed,and an improved greedy algorithm is proposed.A set of real taxi trajectories is used to comprehensively simulate the deployment of RSU to improve the utilization of RSU and reduce vehicle access waiting time within budget constraints.
